Abstract
The utility model discloses an oil-gas separator for an oil tank of a motorcycle. The oil-gas separator comprises a separation chamber and a breather pipe; the upper end of the breather pipe is connected with the top wall of the separation chamber after passing through the bottom wall of the separation chamber and forms a separation cavity with the separation chamber; an inner through hole is formed on the pipe wall of the breather pipe adjacent to the top wall of the separation chamber; the inner through hole is communicated with the separation cavity; an outer through hole is also formed on the wall of the separation chamber; and a backflow hole is formed on the bottom wall of the separation chamber and is communicated with the oil tank. The oil-gas separator for the oil tank of the motorcycle has simple structure, is convenient to install, not only can ensure that the oil supply of an oil line is smooth, and the internal pressure of the oil tank is constant, but also can effectively reduce the emission concentration of oil steam in the oil tank of the motorcycle and reduce the caused pollution and the gasoline waste.
Description
Technical field
The utility model relates to a kind of device of Oil-gas Separation, specifically a kind of deaerator of motorcycle tank.
Background technique
Along with the increase of industrial expansion and pollution, the discharging of motorcycle fuel evaporative pollutant has become problem demanding prompt solution.General and the reservoir port blow-by of the fuel tank cap of motorcycle tank at present, under the situation of fuel tank fuel feeding, oil output back pasta reduces, and prevents to produce in the case degree of vacuum by reservoir port; But under the high situation of external temperature, the temperature of oil raises in the motorcycle tank, adds the volatility of gasoline, and the oil vapor of generation too much can enter in the atmosphere by reservoir port, causes atmospheric pollution.Therefore, in the motorcycle oil supply system, increase the control corresponding device, with the steam output of control fuel oil.Fuel vaporization and discharge control system comprises fuel evaporation storage facility (as activated carbon canister), fuel evaporation purification control apparatus (as the fuel-cut valve) and oil tank fuel evaporation control.
The model utility content
Goal of the invention: the utility model provides a kind of motorcycle oil-gas separator with oil vapor condensation and backflow in the fuel tank, guarantees interior press normal and stable of fuel tank simultaneously, and the discharge amount of reduction fuel evaporation reduces the pollution of motorcycle fuel evaporation thing discharging to atmosphere.
Technological scheme: for achieving the above object, the deaerator of the motorcycle that the utility model provides, comprise separation chamber and breathing pipe, the upper end of breathing pipe is passed separation chamber's diapire and is connected to separation chamber's roof and forms disengagement chamber with the separation chamber, be provided with interior vent at the breathing pipe tube wall near separation chamber's roof, interior vent is communicated with disengagement chamber, also is provided with outer vent on the separation locular wall, outer vent is communicated with the fuel tank inner chamber, and separation chamber's diapire is provided with return port and is communicated with fuel tank.The separation chamber is weldingly fixed in the airtight fuel tank, and reservoir port adopts fuel tank cap airtight.The lower end of breathing pipe is connected to the fuel-cut valve by flexible pipe, and the fuel-cut valve is connected to activated carbon canister by pipeline.
When the vehicle driving road surface of jolting, or gasoline may enter disengagement chamber by return port during climb and fall, because action of gravity, gasoline flows back to fuel tank by return port again, can not enter in the breathing pipe.The lower end of breathing pipe connects the fuel-cut valve and is communicated to activated carbon canister, if the fuel tank intermediate fuel oil evaporates, oil gas absorbs in activated carbon canister by outer vent, interior vent, breathing pipe, fuel-cut valve successively, prevents that oil gas is leaked in the air.
Under the normal use condition of vehicle, fuel tank keeps communicating with atmosphere by this device, and the pressure in the fuel tank is identical with atmospheric pressure, the motor proper functioning.When negative pressure occurring in the fuel tank, by deaerator to the fuel tank tonifying Qi; When producing high pressure in the fuel tank, discharge tank internal pressure by deaerator, avoid tank pressure too high.If the fuel tank intermediate fuel oil evaporates, oil gas is absorbed in canister by return port, interior vent, breathing pipe successively, prevents that oil gas is leaked in the air.
Beneficial effect: the deaerator of motorcycle tank of the present utility model is simple in structure, easy for installation, can guarantee that the fuel feeding of oil circuit is unobstructed, that presses in the fuel tank is constant, can effectively reduce the effluent concentration of oil vapor in the oil tank of vehicle again, the pollution that minimizing causes and the waste of gasoline.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a scheme of installation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, the deaerator of the motorcycle that the utility model provides, comprise separation chamber 1 and breathing pipe 2, the upper end of breathing pipe 2 is passed separation chamber's 1 diapire and is connected to separation chamber's 1 roof and forms disengagement chamber 3 with separation chamber 1, vent 4 in breathing pipe 2 tube walls near separation chamber's 1 roof are provided with, interior vent 4 is communicated with disengagement chamber 3, and oil gas enters breathing pipe 2 through interior vent 4, enters activated carbon canister at last.Also be provided with outer vent 5 on separation chamber's 1 wall, outer vent 5 is communicated with the fuel tank inner chamber, and separation chamber's 1 diapire is provided with return port 6 and is communicated with fuel tank inner chamber 7.
As shown in Figure 2, the deaerator of motorcycle tank of the present utility model is installed in the fuel tank 7, and is fixing by the support welding.The lower end of breathing pipe 2 is connected with fuel-cut valve 8 by first flexible pipe 9, and fuel-cut valve 8 is connected with activated carbon canister by second flexible pipe 10.Oil leaves in the fuel tank 7, and fuel tank cap leakproof fuel cell mouth is opened fuel tank cap, can inject oil; Oil in the fuel tank 7 enters motor through fuel tank switch.When fuel tank 7 internal pressures were excessive or too small, fuel tank 7 communicated with atmosphere through deaerator.When negative pressure occurring in the fuel tank 7, the outer vent 5 by deaerator is to fuel tank 7 tonifying Qi; When producing high pressure in the fuel tank 7, discharge fuel tank 7 internal pressures by deaerator, avoid fuel tank 7 internal pressures too high.If fuel tank 7 intermediate fuel oils evaporate, oil gas is absorbed in activated carbon canister by outer vent 5, interior vent 4, breathing pipe 2 successively, prevents that oil gas is leaked in the air.
The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
